Should I try a muffler mod on my 262xp?

I have it stripped and am putting in a new OEM piston and also crank seals.I've never rebuilt or muffler modded before. All of this is new to me.I've heard before that the 262 mods aren't that much of a gain as the mufflers aren't restricted as the newer saws.Is this right? Any info. on how to mod would be great.

I was going to mod mine but I dont think I am going to now. The saw has a ton of power as is, and I really like the way it sounds right now. I never thought I would find a saw that did not need a muffler mod but this is the saw.
